Here are some things going on this morning in your world of tech:

Shares of Tibco (TIBX) are down $1.66, or 8%, at $19.12, a slight improvement from last night’s after-hours 12% drop, after the company yesterday afternoon warned that revenue and profit in the fiscal Q2 ended this month would miss consensus estimates because of lower-than-expected sales of a data analysis program called “Spotfire,” recently introduced. The company said it was undertaking measures it believes will improve sales.

The stock has gotten three downgrades this morning, that I can see, from Stifel Nicolaus & Co., Mizuho Securities USA, and JMP Securities.

Mizuho’s Abhey Lamba, cut his rating to Neutral from Buy, and cutting his price target to $18 from $25 writes that “Spotfire posted lackluster performance for the third quarter in a row, which we believe is concerning as fundamentals of its end markets are relatively strong.”

“Growth in core infrastructure is not very encouraging as it had very easy compares,” adds Lamba. “While valuation might offer support on the downside, choppy execution will make it difficult for the stock to perform.”

Shares of First Solar (FSLR) are up $2.49, or 4%, at $65.42, after the U.S. Commerce Department late yesterday made a preliminary determination of import duties to be imposed on Chinese solar power panels from Trina Solar (TSL) and others to counter-act alleged dumping by the Chinese firms. Final rates are set to be announced by late August, Commerce said. Shares of Trina are up 11 cents, or 1%, at $10.37.

Shares of AT&T (T) are down 18 cents, or half a percent, at $35.02, after the company late yesterday provided additional details about its proposed merger with DirecTV (DTV) in a filing with the Securities & Exchange Commission. Tuesday was a busy day, as the filing followed AT&T’s announcement in the morning of revised profit outlook for this year as the cost of accelerated handset upgrades takes its tole.

R.W. Baird’s William Power, reviewing the DirecTV filing, notes that AT&T “confirmed that programming costs constitute a significant portion of its planned $1.6 billion in cost synergies,” with programming expenses currently 60% of the cost for AT&T’s “U-verse video revenue.” T estimates that the increased scale will enable it to reduce U-verse programming costs by 20%.

Google (GOOGL) said in a blog post it is expanding its overnight shipping service for online purchases, known as “Google Shopping Express,” to a broad area of Northern California, beyond its initial deployment in the San Francisco Bay Area. Google shares are down 60 cents at $553.91.

The Street continues to ponder Monday’s announcement by chip maker Broadcom (BRCM) that it will seek to get out of the baseband chip business, via sale or a wind-down of the unit.

Drexel Hamilton‘s Richard Whittington this morning raises his rating on the shares to Buy from Hold, and hikes his price target to $45 from $30, and raises hid EPS estimate for the year to $2.58 from $2.40. Whittington calls the proposed disposal of baseband a “strategic milestone.”

He also thinks that “Apple, Google and Samsung home (as well as auto) connectivity initiatives are increasingly liable to spill over into the “new” BRCM.”

Shares of Broadcom are up 18 cents, or half a percent, at $36.06.

Shares of Pandora Media (P) are down 50 cents, or 2.2%, at $24.11, after the company this morning announced that “listener hours,” one of its performance metrics, for the month of May rose by 28%, year over year, to 1.73 billion hours. And Pandora’s share of total U.S. radio listening rose to 9.13% from 7.29%. This is the last time Pandora plans to release monthly data for its metrics, it said.

However, the stock more likely reflects the imminent announcement by the Justice Department it will review the regulation of Ascap and BMI, the licensing clearing houses, which could affect what royalty rates Pandor pays, as related by The New York Times’s Ben Sisario.

Rich Greenfield of BTIG Research was on CNBC this morning with host Simon Hobbs discussing the matter. Greenfield, who has a Sell rating on Pandora, told Hobbs the reality is that probably some content costs will rise for Pandora, putting pressure on its business.
